To all whom 'it may concern: i Y

Be it known that l, SAMUEL fl. WEBB, a citizen ot' the Umtec tltates, residing' at 'Alli-uden, lllebster parish, Louisiana, have invented certain new and useful lmprovements in Rotary Pumps, ot which the .fiollowinpj is a speoilieation.

My invention relates to rotary pumps and consists of ay pluxnlity of l'nenibers which may be in the iorm of dislisfeil'her With llat or Curved or conical proximate faces., and which have reversely Curved Channels efe tending' from the eei'iters to the periphery, a l'iigh rate ot rotative movement being imparted te the movable meniber whereby fluid admitted at the. center is :thrown out ward by centrifugal force in 'the channels of the movable member' and is also forcibly Carried through the channels of the fixed member, as fully set forth hereinafter and as illustrated in the 'accompanying drawing,

in which Figure l is a Sectional elevation of my improved pump showingl its connection ywith an improved motor for driving the moval'ile member; Fig. 2 is a face vieu7 of the movable ordisk member; Fig. 3 is an enlarged section on the line of Fig. 2; Fig'. 4f. an enlarged section on the line --Jc ofi? 2; Fig. 5 a sectional elevation showing a pump embodying a series of iixed and movable elements or members; Fig. 6 is a face view of the movable member of the motor; and Fig.

l a section lllustratmg a dilierent term olf movable member. 1

The apparatus consists essentially ot a fixed member A and a movable member B, mounted to rotate about a suitable axis, as .for instance mounted upon a shaft C to which power is applied to effect the desired rotation, the xed and movable members having their side faces in as closev Contact as possible `Without creating trietional resist ance to the rotation of themovable member.

lin one or both of the side faces of the movable member isa series of curved elianr nels a. which extend outward Ifrom the cen-l tral portion ol. themember andfivhieh are contracted in their cross-sectional area troml -the central to the rim portion ot the mem- Specication of Letters Patent elastic.

The v fluid vvhieh "`i`sfl thrown outward at the periphery of thel member"1Bvr may be diseharged freely into the openair, but in many eases it isdesired to retain it under pressure and the member A there- Jfore is formed into a easing d having a peripheral chamber g/ receiving the fluid dischanged beyond the periphery of the member B, and` from this casing it may be eonducted by a suitable conduit e. f l

llhile any suitable motor may be employed for driving the member B, I prefer to malte use oi one which is built upon the same principle as that of the pump; that 11() able members B ixe'd tothe shaft '0, the

member A forming part of a casing d', to which steam or other fluid under pressure is admitted through an inlet w', and from which it? passes by a conduit c. The proximate faces' of the members A, B lhave curved grooves a', b', reversely arranged as in the case of the pump, but instead-.of contracting toward the outer ends they expand e toward the outer ends.

It. will ofcourse be understood that whatever kind of motor is employed it is one which will rotate the movable member at a very high rate of speed, ten thousand or more` rotations vper minute.

In Fig. 5 I have shown apump in which there is embodied av series of movable members and a series o f fixed members forming part of the main casing. the fixed members being of sullicient thickness to permit of a channel w extending from each peripheral chamber y tothe central or hub chamber 12 the movable members in this case having each a hub j", a rim portion g, and radiating connectin 'arms t5. o v

While have shown in Figsl to 5 the fixed land movable `members having flat proximate'faces and consisting substantially of fiat disks, the proximate faces may be curved or conical, as indicated in the 'crm of the movable member Fig. 7

Without limiting myself to the precise construct-ion and arrangement of parts shown, I claim:

1. A rotary ump 'comprising a plurality of 'members with radiating channels upon 'their proximate faces eacheorresponding to part of a (parabolic curve those of one mem-4 member-in which the channels are situated.

3. A rotary pump having fixed and rotatable members with radiating curved channels in their proximate faces, each of said channels having a face 1 substantially perpendicular to that.of the member containing it, the faces 1 of the channels in one member crossing those of the other substantially at right angles at all meeting points.

, 4. A rotary pump comprising fixed and rotatable members having radiating curved channels in their proximate faces, each of said channels` having faces l and 2 which are respectively perpendicular andl at an acute angle to the face of the member containing the same, the faces l of the channels in one member crossing the corresponding faces of the channels of the other member substantially at right angles at all meeting points.

5. The combination in a pump vof fixed and rotatable members, each rotatable member having radiating channels at each sidefa'ce'corresponding to part of a parabolic curve, each fixed member having radiating channels corresponding to part of a parabolic curve and arranged in an opposite direction to those upon the movable member, the faces of the members being in close proximity, a casing forming part of the fixed member and having a central hollow hub and a peripheral chamber and inlet and out-let opemngs.

G. A rotary pump comprising a plurality of members with radiating channels upon their proximate faces, each' corresponding to part of a parabolic curve, said channels contracting toward their outer ends, those of one member curved in a reverse direction to those of the other, and means 'for imparting rapid rotation to one of the memers and retaining `the other in a fixed position.

In testimony whereof I aiix my signature inv presence of two Witnesses.
